Maintenance 86 Maintenance Care of the projector Your projector needs little maintenance. The only thing you need to do on a regular basis is to keep the lens and case clean. Never remove any parts of the projector except the lamp. Contact your dealer if other parts need replacing. Cleaning the lens Clean the lens whenever you notice dirt or dust on the surface. • Use a canister of compressed air to remove dust. • If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens cleaner and gently wipe the lens surface. • Never use any type of abrasive pad, alkaline/acid cleaner, scouring powder, or volatile solvent, such as alcohol, benzene, thinner or insecticide. Using such materials or maintaining prolonged contact with rubber or vinyl materials may result in damage to the projector surface and cabinet material. Never rub the lens with abrasive materials. Cleaning the projector case Before you clean the case, turn the projector off using the proper shutdown procedure as described in "Shutting down the projector" on page 70 and unplug the power cord. • To remove dirt or dust, wipe the case with a soft, lint-free cloth. • To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral pH detergent.

Maintenance 87 Lamp information Getting to know the lamp hour When the projector is in operation, the duration (in hours) of lamp usage is automatically calculated by the built-in timer. The method of calculating the equivalent lamp hour is as follows: Total (equivalent) lamp hour = 1 (hours used in Economic mode) + 4/3 (hours used in normal mode) See "Setting Lamp Mode eco function as Economic or SmartEco mode" below for more information on Economic mode. The lamp hour in Economic mode is calculated as 3/4 of that in Normal mode. That is, using the projector in Economic mode helps to extend the lamp hour by 1/3. To obtain the lamp hour information: 1. Press MENU/EXIT and then press / until the SYSTEM SETUP: Advanced menu is highlighted. 2. Press to highlight Lamp Settings and press MODE/ENTER. The Lamp Settings page displays. 3. You will see the Equivalent lamp information displaying on the menu. 4. To leave the menu, press MENU/EXIT. You can also get the lamp hour information on the INFORMATION menu.
